If I do so and then proceed by running powertop on battery, intel_pstate complains about turbo not being available, a usb device disconnects, a while later Nouveau resumes kernel object trees, Bluetooth reconnects and nouveau suspends again. The commands are: # echo auto > /sys/bus/pci/devices/0000\:00\:1c.4/power/control # grep . /sys/bus/pci/devices/0000:0{0:1c.4,1:00.0}/power/{control,runtime_status} The latter returns auto, suspended, auto, suspended before running powertop, and on, active, auto, suspended after running powertop.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
